虽然在从智能电话到游戏控制器的设备中很常见，但振动触觉反馈通常限于在触觉表面上提供均匀的感觉。我们提出了一个触觉界面的基础上出现的物理效果的粒子干扰与振动触觉和形状变化的输出，它可以在空间中扩展，以创建触觉表面和设备的形状和振动触觉响应本地化到设备的一部分。本文概述了这项技术背后的物理原理，并提出了详细的性能指标从一个工作原型。这些包括空气压力和电动机功率和振动幅度和频率之间的关系的实验表征，这表明它是可能的控制振动触觉的幅度和频率独立。
Whilst common in devices ranging from smart-phones to game controllers, vibrotactile feedback has generally been limited to providing a uniform sensation across a tactile surface. We propose a haptic interface based on the emerging physical effect of particle jamming with both vibrotactile and shape changing outputs, which can be extended in space to create haptic surfaces and devices with shape and vibrotactile responses localised to one part of the device. This paper gives an overview of the physical principles behind this technology and presents detailed performance metrics obtained from a working prototype. These include experimental characterization of the relationships between air pressure and electric motor power and vibration amplitude and frequency which show that it is possible to control vibrotactile amplitude and frequency independently.
